Portable Vibration Calibrator LPVC-A10

Portable Vibration Calibrator LPVC-A10 is a tabletop unit with standard sine signals at continually varying frequency from 10 Hz to 1280 Hz. LCD digital panel displays defined amplitude of the acceleration, velocity and displacement. Either horizontal or vertical vibration can be generated. It is an all in one unit combining sine signal generator, power amplifier, standard transducer and a shaker.
